Where to get information about dyckia's

I only know of a few places to go for information about dyckia's.
Good infor is hard to come by.

The first place is Dyckia Brazil at http://dyckiabrazil.blogspot.com which is a blog by Constantino Gastaldi in Brazil who grows that seen like all dyckia sp found in Brazil and some hyb.

The second place is

Florida Council of Bromeliad Societies at

 http://fcbs.org/ 

Lots of photo's plus you can search the species database and the other database's they have.

and

Bromeliad Society International web-site at

http://bsi.org/

 You can look at the pictrues. One of the best thing on this site is the

Bromeliad Cultivar Register search. You need to be a BSI member to see the

recent back issues of the BSI Journal. These issues are available as Adobe Acrobat.
Also Bromeliad Binomial.
